This Sigma Macro 150mm F2.8 EX DG HSM is a large aperture medium macro lens ideal shooting the smaller things in our world that exist virtually unseen. A macro lens is one which will focus on a subject close enough to render it life-size on the image plane in your camera. It also has a flat field front lens element so that it can shoot images of flat objects such as artwork or postage stamps and be tack sharp all the way across the image. With HSM (Hyper-Sonic Motor) a quiet & high-speed auto focus is ensured. Two SLD (Special Low Dispersion) glass elements provide optimum color correction and sharpness throughout the entire range and Super Multi-layer coating reduces flare and ghosting. It is also compatible with Sigma APO Tele Converters.
Ideally suited for taking pictures insects or other small creatures, but it is also the perfect focal length for facial portraits rendering the best perspective of the human face. This greater distance also allows the photographer more flexibility in lighting the subject with natural light reflectors. So don’t miss the tiny insects, flowers of the world or the details in a stamp or coin collection or a piece of embroidery all of which are seldom noticed but offer a fascinating world if you look closely enough. Capture them with the Sigma Macro 150mm F2.8 EX DG.
- Designed for use with full frame digital SLR cameras. May also be used with smaller APS-c size sensors with a corresponding effective increase in focal length to about 225mm with most cameras
- Focuses down to 1:1 magnification ratio at its closest working distance of 15 inches

Comments about Sigma Sigma 150mm f/2.8 EX APO DG HSM Macro Lens F/Nikon:
Great for maintaining high optical performance from infinity to close up 1:1 macro photos without accessories so you can get those great up close and personal shots of insects that are shy Pros.The picture quality is impressive and the ability to shoot 1:1 macro opens a new world of details for you. I was impressed with the quality that the sigma dedicated to this lens. It's kind of lens that does not work in post processing. The colors, the contrast is excellent, in a warmer tone than the nikon lenses. My D90 has an optimal communication with the lens, because it always hits the right exposure.CONS. it is only ok for medium telephoto work Auto focusing. It's slow, a little slower than expected, but not a shock, nor is AF needed for all my macro work or most of my telephoto work. For medium telephoto, this lens lacks in key areas. Compared to my 70-200/4 L in controlled conditions and at similar settings, the Sigma demonstrates far less sharpness, detail, color and contrast than the Canon zoom. Of course, my Canon zoom is slower than Sigma by a stop, however the Sigma prime takes a back seat to the Canon zoom in the medium telephoto department.
